WHEEL.

Specification of Letters letent.

Patented July 6,1909,

Application filed. October 10, 1907. Serial No. 396,837.

To all whom it may concern: r

Be it known that 1, JAMES G..MAXWELL, a citizen of the United States,residing at Washington, county of Washington, and. State ofPennsylvania, have invented certain" new end useful Improvements inWheels, of which the following is o. specification, referonce being hadtherein to the accompanying d rowin s.

This invention relates to Wheels, especially adopted tor use upon motorvehicles, and its primary object is to provide a resilient or cushionedwheel of strong, effective and du reble construction. Another object oftlrls'inventionis to provide a. wheel that Will'not skid when e vs someis passing around a. curve.

A. further object of the invention is to provide e Wheel with e tirewhich cannot be punctured, and which at the same time will possess theresiliency of the ordineryypneu- The invention comprises owheel providedwith tubular spokes, a rim carried by said spokes, spring pressedplungers Within said spokes, a plurality of to lower-plates secured tothe outer ends of said plungers, end a. solid elastic tire secured tosaid followerpletes.

The invention also includes :1 Wheel huh of novel form, and improvedmeans for securing the spokes thereto.

The construction of the improvement Will. be fully described hereinafterin connection with. the uccol'npenying drawing which forms a part ofthis specification, and its novel i'eetures of construction will he setforth in the appended claims.

in the drawing: Figure 1 is a fragmentary side elevation partly insection, and partly broken e1 oy, of :1. Wheel embodying the invention,and Fig. 2 is a longitudinal transverse section. of the some.

The wheel hub preferablyconsists of seporehlc sections 1 end 2, suchformed with scmi-oirouler openings which register to provide redialtapered sockets 3 to receive toperod tenons 4t projecting from the innerends of tubular spokes 5. The huh sections 1 and 2 are connected, bybolts (5 which also secure the tenons 4 within the sockets 8. Withineach of the hollow spokes is e cylindricel plunger 7 cirounderentiellyreduced at its outer end 8 to form o shoulder 9. The outer open end ofeach of the spokes is intcrceive the spokes.

tion, and adopted to fit with shown inFig. 2. A solidtire 14 preferablyby. the U-shoped .follower plotcs.

holly ecrew-thresded to receive a threeded bushing 10* egeinst which theshoulder t? beers to limit the outwerd movement of the plunger. A. coilspring 11 is interposed hetiveen the inner end of eech plunger, end theinner closed end of the spo to, said springs serving to project theplungers outward.

A rim'12 of u shope'in crossse'ction is secured to the outer ends of thespokes 5, sold run. being formed with, threaded openings to re 'Tlo thereduced cute. ed 8 of each of the plunger ie-secureo e tel. iower plete13 also of Ushepe in cross-teen in the rim 12, us

of ruhloer is fitted withinthle groove formed The huh sections areprovided "with. suitable bearings 15 and litter the vehicle axleconnections.

The utility and o emtion of the Wheel coirstructed as thus c escrihedwill be readily understood. 'As the-tire 14 is solid ell-"lie hility ofannoyance by punctures is avoided. The yielding of the plungers "7against the tension of the springs 11 imports the desired resiliency tothe tire, and es eech of the plungers acts independently, a continuousyield ing or cushioning of the tire is insured.

Having nowdescribed my invention What i I churn its new, is:-'--

' A "wheel comprising 9. huh, hollo s tubular spokes having their innerends closed end secured to Sift-id 'liuh, s rim substantially I shepcdin cross section hcvlng the outer open ends'ol seid. spokes threadedtherein, e follower-member extending; with said rim, o tire securedWithin. and projecting from said.

member, o bushing tireeded in. the outer open. end of each of saidspokes and consti toting :1; stop, it lun 'or mounted in each of soldspokes and. owing u. reduced outer end extending; through the bushing:and direc 5 secured to said member, said enlarged poi? tions of soldpioneers adopted to shut egninst said bushing" wherehy the outwardmovements of the plunger are arrested, and u com prossion spring'wi thineach of the spokes interposed between the inner end of the piston, andthe closed end of the spoke, said spring normally nmintoiuing thefollower projected;
